http://www.flickr.com/photos/johnandnancy/2176174998/ Bought this 10" speaker off of musicman7722 (thanks!). It's an avatar neo 10" (modded eminence I believe). Anyway, I can't figure out which side of this speaker is positive and which is negative? There is what might be a slight "- -" marking and solder on the right hand speaker terminals (see picture). Does this signify the negative terminal? Looks pretty good in the picture. To the naked eye it's a little less apparent.
